The author has switched up some of the TOC and is working hard to ensure that the flow of the book is not disturbed by these changes.

I feel that, at least in the early iterations of a MEAP, the author(s) should be able to make any alterations they feel would enhance the product. I realize that people, myself included, buy MEAP in part on the strength of the TOC and product description, but for me it is a guide on whether a topic of interest will be covered, and not whether one topic would more naturally follow another.
